Who Are You was released as Polydor 2490 147 (WHOD 5004) August 18, 1978. It reached #6 in the U.K. Released in the U.S. as MCA 3050 on August 25, 1978, it reached #2.

[In addition to the standard releases, Who Are You was also released in red vinyl in Canada, a picture disc in the U.S., two 1981 "Super Disk" versions on the Direct Disk Labs label (SD 16610), one regular and one requiring a DBX decoder, and a 1992 Mobile Fidelity Sound Labs gold CD (UDCD 561). Who Are You went platinum (1 million in U.S. sales) within four weeks of its release and reached double platinum in 1993.]

[Who Are You had part of its genesis in another attempt to revive the 1970 Lifehouse project (for more on that, see the liner notes to Who's Next). According to Pete, Roger had pushed him to have another try at the project and he wrote a new draft of the screenplay. This one is a sequel to the previous Lifehouse story. Set 200 years after those events, it concerns another attempt to stage a huge rock concert and feed it to all the people on the Grid in order to free them from the necessity of the experience suits. Those holding the concert are aided by the "musos," a group that worship music and who are opposed to Plusbond, the corporation that runs the Grid. The woman who runs Plusbond, meanwhile, is promising that if people do not abandon their suits, the "perfect one" will soon arrive to lead them to spiritual salvation. Prior to Keith Moon's death, The Who announced plans to make four films, The Kids Are Alright, Quadrophenia, McVicar and Lifehouse. Lifehouse was to have been directed by Nicholas Roeg, the director of Performance and The Man Who Fell To Earth. Pete and Nicholas had trouble agreeing to the direction of the script and then had a falling out in 1980 which again scuttled plans for the film.]
